> The language itself is extremely poor
> I think this is not something most Python users are aware of
These two statements are contradictory. If it was indeed so "poor", people would notice :) If they instead increasingly adopt it (out of appreciation, not because they are lobbied into doing it) it becomes really difficult to logically demonstrate that it's a poor choice. Software development is a very efficient market. Everyone is (or can be) aware of (almost) everything. So if most people (including experienced devs) gravitate towards a certain technology, the only acceptable explanation is that the technology, as a whole, is good.
Deconstructing and pointing out the flaws of the individual components is a common flawed thought process IMHO. Python is great despite all the issues you point out. To me this is equivalent to comparing individual components when shopping for a product, missing the fact that it's the ensemble of all those (flawed) components that make the product (or the language, in this case) work. The easy syntax, the packages, the community, those are all things that make "weird scoping rules" pretty much irrelevant.
